9f92dff354 Bluetooth: controller: Fix issue with duration/max number of adverts
When a maximum duration or number of advertisements has been set for an
advertisement set, we will exceed that limit if the last advertisements
happen to be overlapping (ie. we have two primary advertisements pointing
to the same AUX_ADV_IND).

We now have a check in the ticker_cb that will ignore the callback if the
state is such that advertisement would have been stopped if ull_adv_done()
had been allowed to run in the meantime.

8a5273525e nrf52_bsim: Convert from a nRF52832 to a nRF52833
The nRF HW models have been updated to correspond to a 52833 instead
of a 52832. Let's follow them.

The motivation for the change is to enable proper BIS encryption support
(for BT LE Audio ISO).

Changes:

* Point in manifest to latest HW models

* SOC_COMPATIBLE_NRF52832 has been removed, and SOC_COMPATIBLE_NRF52833
added in its place (with no uses at this point)

* Where SOC_COMPATIBLE_NRF52832 was used to set encryption like for a 52832
(to avoid using the MAXPACKETLENGHT), we set the condition to just
SOC_NRF52832.
Note: The MAXPACKETLENGHT register exists in the new simulated nrf52833,
thought it does nothing.

* In the BLE ctrl LLL radio HAL, all macros are renamed accordingly
(timings are NOT changed).

* Board dts definition now refers to the 52833 soc definition. New 52833
features set as not supported by now.

60b1f2b36b Bluetooth: controller: Reduce ISO peripheral CIS establishement delay
New LLCP will process the CIS establishement in the TX path, meaning it
will only process once every ACL connection interval.
If ACL connection interval is significantly longer than the ISO
interval, CIS packets corresponding to the ACL connection interval will
be lost. This may cause latency in audio rendition.

By processing the CIS establishment in the RX path, notification will be
sent immediately, and audio path is enabled fast to reduce latency.

When a CIS fails to establish, the controller shall complete the
procedure by sending a CIS_ESTABLISHED event containing the error.

a982c9f9f6 Bluetooth: controller: Start CIG immediately if instant is next event
To be able to timely start the first CIS/CIG, if the requested instant
is the next connection event, call ull_peripheral_iso_start directly
from rp_cc_state_wait_rx_cis_ind instead of waiting for next time
through the state machine.

To enable ULL/LLL to prevent adding latency when LLCP is waiting for
instant, local- and remote procedures with instant now expose a function
for checking this state.

Fixed event_counter function to prevent one-off in RX path. Unified to
use single function ull_conn_event_counter.
